HERBERT H. HULL, OF CLEVELAND, OHIO.

PAINT-CAN.

SPECIFICATION forming part of Letters Patent No. 242,326, dated May 31, 1881.

Application filed October 26, 1880.

To all whom it may concern:

Be it known that I, HERBERT H. HULL, of Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented a new and useful Improvement in Cans for Paints; and I do hereby declare that the following is a full and exact description ofthe same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention has for its object certain improvements in the construction of cans or vessels for containing mixed or semi-duid paints, so that by means of a movable diaphragm within a cylindrical can a portion or the entire contents ofthe can may be expelled without removing either head from the vessel. I am aware that this has been done in several instances of patents now existing, and I do not claim as my invention the broad principle involved, my object being to construct a can more compact and simple than others of its class, and which shall be equally efficient in its operation.

The drawing Figure l is an elevation ot my improved paint-can, having a portion of 011e side broken away to exhibit the interior and the construction and operation ofthe rod and diaphragm.

A is the head ofthe can, B the rod having a thread cut on its surface and passing through the diaphragm C.

The crank D is detachable, and is placed upon the rod B for the purpose ot' rotating it, and thus moving the diaphragm C in either an upward or downward direction. Vhen moved downward the paint contained in the lower part of the can, beneath the diaphragm,`

section in Fig. 2) is held in place by grooving the tin, so as to cause an indentation of the can to be forced into a shallow groove made in the periphery ot' the false bottom, thus pre venting its moving out of place.

The diaphragm is prevented from turning with the revolution of the threaded rod by grooves a b, which are cut to fit upon projections a b formed by folding the edges of the sheets ot' metal of which the can is made inwardly, as shown in Fig. 3. This may be done on only one side, if desired, where the can is made of but one strip ot1 tin or other suitable material.

-The rod B is held in place by a washer, d, upon the under side of the can, where it is covered by a small circular piece of metal, d', soldered to the bottom, which prevents any outward injury to its operation.

Having thus described my invention, what I cla-im as new, and desire to secure by Letters Patent, is-

1. A can having a cylindrical body withinternal ribs, a b', made by folding together the meeting edges of the parts forming said body, and provided with a diaphragm, C, of similar shape, with grooves a b in its periphery tittin g upon said ribs a b', whereby the diaphragm is adapted to be moved up and down within the can without its turning by means of a screw-shaft passing centrally through it, substantially as described and' shown.

2. A can wherein the lower end of its screw shaft B is passed through both the false and true bottom of the can, and by means of plate d and cap d held from vertical displacement, substantially as described and shown.

This specitieation signed and witnessed this 2d day of June, 1880.
